So it seems that this commit fixes the issue for me:

commit 56f8aefa0bb94b256d68b99bc8db665ed6813bcf
Author: Sami Wagiaalla <swagiaal@redhat.com>
Date:   Fri Sep 18 15:01:41 2009 -0400

    Check has_stack_frames() before calling find_pc_line.


The commit is not yet on archer-jankratochvil-fedora12 though.
